How much turntable hum is normal?
It’s important to note that some humming is a reality of analogue gear — if you’re only hearing the hum when you’ve got the volume cranked up to 88, then it’s within normal range.
What causes 60Hz hum?
There are two basic types: 120Hz buzz, typically caused by ground loops, and 60Hz hum, typically a result of poor shielding, cable problems, or close proximity to strong magnetic fields.
What does a 60Hz hum sound like?
It buzzes in a medium monotone and it almost sounds like a fly or bee buzzing around. But it’s a light and it makes you feel more comfortable than a bug. You know that some street lights do this as well, in different tones with each one.
What does 60hz hum sound like?
The electricity hum (also called the “mains hum”) emerges because electricity runs on alternating current (AC), which transposes voltage in the pattern of a sine wave. In the US, the frequency of this current is 60 Hz, which creates a tone almost exactly halfway between A♯ and B.
How do I ground my turntable?
How to Ground a Record Player
- Turning off the power of the player.

- Locating the Ground Terminal on the Amplifier.
- Connecting the Ground Wire to the Amplifier Ground Terminal.
- Drop the Ground Wire with the Spade Connector to the Grounding Terminal.
- Connect power and check operation.
Is 60 cycle hum normal?
Typically, alternating current that is found in most power lines has a frequency of 60hz. Interestingly enough, power cables and audio cables do not like to play nice together, which results in a hum when they are too close without proper shielding or isolation.
